Tonic doesn't do a particularly good job at abstracting away the details of reflection. I wouldn't describe having to think about "file descriptor sets" as stupidly simple.

I would argue it's still quite simple: it's an extremely powerful (and complex) feature and all you have to do is add a few lines of code. But yes, ergonomics could be improved and it would make it even better if the file descriptors could be generated together with the rest. Adding tonic-reflection as a feature to tonic itself would probably solve this.

My take here would be options... I know it's not Rust's fault, but the move to remove the required statement between proto2 and proto3 was a mistake IMHO, this is particularly bad in Rust as there is no cheeky way around options. Deeply nested messages create an "if let" / "match" hell very quickly.

btw, you have explained all nicely, but at 11 minutes you are executing the --bin client without executing --server to the viewer and that can be missleading since -bin server needs to be up priot to the client execution. Just saying it in case there are people stuck at that step and they did not think of this at all since they are noobs just like myself

Yeah a crate is a collection of code, similar to a module, package, or library in some other languages. In JavaScript you use npm to install a module. In Python you use pip to install a package. In Rust you use cargo to install a crate. I believe Rust chose this word specifically to avoid confusion with other languages, since while a package, module, and crate are all conceptually the same thing (a bundle of code), they do have some slight differences in their rules.

The Arc seems unecessery. U dont need to refrence count it. Since its only used in the server

@shifteleven

3 ай бұрын

I’m not a compiler, but I think it is needed since the counter is shared in the asynchronous trait context. And while it’s used in the server, I assume the server is multithreaded and two threads could try to access the value at the same time. The arc is then ensures proper memory access and updating

​@@nevokrien95 it's executed inside a tokio runtime, which is async. One of the drawbacks of async rust is once it's async, you have to use thread safe mechanics such as Arcs, even if the executor is mono threaded. I'm no expert but I believe the code would not compile with a state not wrapped in an Arc.

@nevokrien95 the reason for having an rc wrapping an object, is to free the associated resource as soon as we stop referencing it in our program. This is not just boilerplate: its more than what C does. In C you would be expected to manually keep track of ownership of an object in order to free its memory (and release its resources)

@irlshrek

@@nevokrien95 you could use RwLock if the thing youre working with is going to be read from much more than written to. Youre right though that it could be a Mutex. the difference is that with RwLock you dont have to wait for another thread (or RPC call, as it were) to release the lock if its just reading, whereas with a Mutex, you would. The draw back though is that if you have a BUNCH of threads reading the RwLock, you may struggle to get a lock to write to it. Also RwLock has a bit more developer overhead.

It really depends on what you're doing. If you have any API that you need clients for across multiple languages, it is a huge help because it's language agnostic. It's also been very useful for me because at work we use it to stream data extremely quickly which is important for our use case. That said, if your project does not need to scale multiple languages or the speed of rest APIs works for your use case, it is faster to get rest set up. I will say though, as a small team, grpc saves a lot of time we would have had to spend documenting our API if we were using rest, whereas proto definitions are by nature almost self documenting.

Yes but JSON is weakly typed, so you need something like OpenAPI to actually make it usable. The complexity is quite high, because JSON is broken in a fundamental way and therefore requires massive amounts of tooling to make somewhat decent.
